Notes: 1. The tolerance limits are specified after calibration with stable voltage and temperature.
For the behavior of the tolerance limits if temperature or voltage changes after calibration, see following
section on voltage and temperature sensitivity.
2. The tolerance limits are specified under the condition that VDDQ = VDD and that VSSQ = VSS.
3. Pull-down and pull-up output resistors are recommended to be calibrated at 0.5 × VDDQ. Other calibration
schemes may be used to achieve the linearity spec shown above, e.g. calibration at 0.2 × VDDQ and 0.8
× VDDQ.
4. Not a specification requirement, but a design guide line.
5. Measurement Definition for RTT:
Apply VIH (AC) to pin under test and measure current I(VIH(AC)), then apply VIL(AC) to pin under test
and measure current I(VIL(AC)) respectively.
VIH(AC) − VIL(AC)
RTT =
I(VIH(AC)) − I(VIL(AC))
